Common Issues Common Problems and Solutions The air conditioner is operating normally when: • You hear a pinging noise. This is caused by water being picked up by the condenser on rainy days or in highly humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency. • You hear the thermostat click. This is caused by the compressor cycle starting and stopping. • You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit. • You hear the fan running while the compressor is silent. This is a normal operational feature. The air conditioner may be operating abnormally when: Problem Possible Causes What To Do ■ The air conditioner is unplugged or • Make sure the plug is completely plugged into not plugged in completely the outlet The air conditioner does not operate at all Air conditioner does not cool ■ The fuse is blown/circuit breaker is • Check the fuse/circuit breaker box and replace triggered the fuse or reset the breaker ■ Power failure. • In the event of a power failure, set the power control to OFF. When the power is restored, wait 3 minutes to restart the air conditioner to prevent the compressor from overloading ■ Air flow is restricted • Make sure there are no curtains, blinds, furniture or other obstacles in front of the air conditioner ■ The THERMOSTAT may not be set cool enough • Turn the knob to a higher setting. The highest setting provides maximum cooling ■ The air filter is dirty. • Clean the filter at least every 2 weeks. Refer to the “Care and Maintenance” section (p.11) of the manual. ■ The air conditioner was just turned on. • After the air conditioner is turned on, you need to give the air conditioner some time to cool the room. ■ Cold air is escaping. • Check for open furnace floor resisters and cold air returns. • CLOSE the air conditioner vent Ice appears on the air conditioner. ■ Cooling coils are iced up • See Ice appears on the air conditioner below ■ The cooling coils are iced over. • Ice may block the air flow and obstruct the air conditioner from properly cooling the room.
